Abstract
Description
- The disclosure relates to a sealed assembly and to a method of unsealing the sealed assembly.
- Fluids are often contained within a cavity defined by two separable components. For example, for automotive applications, a first component, such as an engine block, and a second component that is separable from the first component, such as an oil pan, may be mated together to define a cavity configured for holding oil. Often, such components are sealed to one another with a sealant to prevent fluid loss from the cavity during vehicle operation.
- A sealed assembly includes a first component having a first flange, and a second component having a second flange matable with the first flange. The sealed assembly also includes a sealant disposed between and along the first flange and the second flange such that the first component is sealingly mated to the second component. Further, the sealed assembly includes a wire disposed within the sealant, wherein the wire is configured for unsealing the second component from the first component.
- In one embodiment, the first component is formed from a first material, and the second component is formed from a second material that is different from the first material. Further, the second flange has an inner edge and an outer edge spaced apart from the inner edge. The sealed assembly also includes a room-temperature vulcanized sealant disposed between and along the first flange and the second flange such that the first component is sealingly mated to the second component. The wire is disposed within the room-temperature vulcanized sealant along an entire perimeter of the second flange, and the wire spaces the first component apart from the second component. The wire includes a handle configured for pulling the wire through the room-temperature vulcanized sealant and extends from the second flange past the outer edge. The sealed assembly further includes a plurality of fasteners configured for attaching the second flange to the first flange and disposed between the inner edge and the outer edge. The wire at least partially surrounds each of the plurality of fasteners and is disposed between the outer edge and each of the plurality of fasteners. Further, the room-temperature vulcanized sealant is severable by the wire so that the first component unseals from the second component.
- A method of unsealing a sealed assembly includes applying a sealant composition onto a wire, wherein the wire is disposed between and along a first flange of a first component and a second flange of a second component. After applying, the method includes curing the sealant composition to form a sealant between the first component and the second component such that the second component is mated to the first component to thereby form the sealed assembly. After curing, the method includes pulling the wire through the sealant to sever the sealant and thereby unseal the sealed assembly.
- The detailed description and the drawings or Figures are supportive and descriptive of the disclosure, but the scope of the disclosure is defined solely by the claims. While some of the best modes and other embodiments for carrying out the claims have been described in detail, various alternative designs and embodiments exist for practicing the disclosure defined in the appended claims.
-
FIG. 1 is a schematic perspective exploded illustration of a sealed assembly including a first component, a second component, and a wire disposed therebetween; -
FIG. 2 is a schematic perspective exploded illustration of a partial view of the first component and the second component ofFIG. 1 , wherein the wire is disposed on the second component; and -
FIG. 3 is a schematic flowchart of a method of unsealing the sealed assembly ofFIGS. 1 and 2 . - Referring to the Figures, wherein like reference numerals refer to like elements, an exploded view of a sealed assembly is shown generally at 10 in
FIG. 1 . The sealedassembly 10 may be useful for vehicles, such as automotive vehicles, that may require containment of fluids within a sealed cavity. However, the sealedassembly 10 may also be useful for non-automotive applications including, for example, marine, household, and aviation applications wherein any fluid may be contained within the sealed cavity. - As shown in
FIG. 1 , the sealedassembly 10 includes afirst component 12 having afirst flange 14. For example, for automotive applications, thefirst component 12 may be an engine block of an internal combustion engine (shown inFIG. 1 ), and thefirst flange 14 may extend perpendicularly from thefirst component 12 and be configured for attachment to asecond component 16, as set forth in more detail below. For non-automotive applications, thefirst component 12 may be a bathtub (not shown) or window frame (not shown). Further, thefirst flange 14 may have afirst sealing surface 100 that is configured for sealing to thesecond component 16. Thefirst component 12 may be formed from a first material, such as, but not limited to, a metal. By way of a non-limiting example, the first material may be aluminum. - With continued reference to
FIG. 1 , the sealedassembly 10 also includes thesecond component 16 having asecond flange 18 matable with thefirst flange 14. For example, for automotive applications, thesecond component 16 may be an oil pan (shown inFIG. 1 ), a rear engine cover (not shown), or any other element configured for attachment to thefirst component 12. For non-automotive applications, thesecond component 16 may be, for example, a pane of glass (not shown) matable to thefirst component 12, e.g., the bathtub (not shown) or window frame (not shown). Thesecond flange 18 may also extend perpendicularly from thesecond component 16, and may be configured for attaching to thefirst flange 14, as set forth in more detail below. In particular, thesecond flange 18 may have asecond sealing surface 200 that is configured for sealing to thefirst sealing surface 100. In addition, thesecond flange 18 may have aninner edge 20 and anouter edge 22 spaced apart from theinner edge 20. - With continued reference to
FIG. 1 , thesecond component 16 may be formed from a second material that is different from the first material. Therefore, thefirst component 12 and thesecond component 16 may be formed from different materials so that the sealedassembly 10 is a composite part. Alternatively, the second material may be the same as the first material. Suitable second materials include, but are not limited to, polymers such as polyamides, e.g., nylon, and metals, such as aluminum. Therefore, in one non-limiting example, the sealedassembly 10 may include an aluminum engine block, i.e., thefirst component 12, and a nylon oil pan, i.e., thesecond component 16. - Referring now to
FIG. 2 wherein the sealedassembly 10 is also shown in an exploded view, the sealedassembly 10 further includes asealant 24 disposed between and along thefirst flange 14 and thesecond flange 18 such that thefirst component 12 is sealingly mated to thesecond component 16. Thesealant 24 may be selected from any suitable sealant, such as, but not limited to room-temperature vulcanized sealants and silicone sealants. As used herein, the terminology “room-temperature vulcanized sealant” refers to a two-component material system, e.g., including a base component and a curing agent reactive with the base component, that is cured at ambient temperature, and generally applied tocomponents vulcanized sealant 24 may provide a fluid-tight seal between thefirst component 12 and thesecond component 16. A suitable example of the room-temperature vulcanizedsealant 24 is room-temperature vulcanized silicone rubber. - With continued reference to
FIG. 2 , the sealedassembly 10 further includes awire 26 disposed within thesealant 24, wherein thewire 26 is configured for unsealing thesecond component 16 from thefirst component 12. That is, as set forth in more detail below, thewire 26 may aid in disassembly of thesecond component 16 from thefirst component 12 during, for example, maintenance operations of the sealedassembly 10. - As best shown in
FIG. 2 , thewire 26 may be disposed along aperimeter 28 of thesecond flange 18. That is, thewire 26 may circumscribe thesecond component 16 along thesecond flange 18, and may therefore also circumscribe thefirst component 12 along thefirst flange 14 when thefirst component 12 is mated to thesecond component 16. More specifically, thewire 26 may have afirst end 30 including ananchor 32, and asecond end 34 spaced opposite thefirst end 30. Thesecond end 34 may include ahandle 36 configured for pulling 60 (FIG. 3 ) thewire 26 through thesealant 24 and extending from thesecond flange 18 past theouter edge 22. Therefore, as set forth in more detail below, thewire 26 may sever, e.g., slice through, thesealant 24 when thehandle 36 is pulled in a direction (represented generally byarrow 38 inFIG. 2 ) substantially parallel to thefirst sealing surface 100 and thesecond sealing surface 200. - For example, with continued reference to
FIG. 2 , the sealedassembly 10 may further include a plurality offasteners 40 configured for attaching thesecond flange 18 to thefirst flange 14. The plurality offasteners 40 may be, by way of non-limiting examples, bolts, screws, and the like. Further, as best shown inFIG. 1 , thesecond flange 18 and thefirst flange 14 may define a plurality ofholes 42 therein each configured for receiving a respective one of the plurality offasteners 40. Therefore, when fastened, each of the plurality offasteners 40 may extend through a respective one of the plurality ofholes 42 defined by thefirst flange 14 and thesecond flange 18 to thereby attach thesecond flange 18 to thefirst flange 14. - As best shown in
FIG. 2 , theanchor 32 may be attached to or surround one of the plurality offasteners 40, and thewire 26 may be disposed adjacent to the plurality offasteners 40 along thesecond flange 18. That is, theanchor 32 may be configured as a ring, and one of the plurality offasteners 40 may extend through theanchor 32 to thereby attach thefirst end 30 of thewire 26 to thefastener 40. More specifically, each of the plurality offasteners 40 may be disposed between theinner edge 20 and theouter edge 22. Further, thewire 26 may at least partially surround, e.g., may be bent around, each of the plurality offasteners 40 and may be disposed between theouter edge 22 and each of the plurality offasteners 40. - That is, as described with reference to
FIG. 2 and as set forth in more detail below, thewire 26 may be bent, e.g., into a rigid, bent configuration (shown generally at 44 inFIG. 2 ), to have a shape congruent with thesecond flange 18. Therefore, thewire 26 may be placed onto thesecond flange 18 in the rigid,bent configuration 44 in preparation for forming the sealedassembly 10. As such, thewire 26 may space thefirst component 12 apart from thesecond component 16. That is, as assembled, thewire 26 may be disposed within thesealant 24, and may be sandwiched between thefirst component 12 and thesecond component 16 along thefirst flange 14 and thesecond flange 18. - The
wire 26 may be selected from any material suitable for bending and retaining the rigid,bent configuration 44. For example, thewire 26 may be steel wire and may have athickness 46 of from about 0.3 mm to about 0.7 mm, e.g., about 0.5 mm. - Referring again to
FIG. 2 , in operation, thesealant 24 may be severable by thewire 26 so that thefirst component 12 unseals from thesecond component 16. For example, thesealant 24 may be partially- or fully-severable by thewire 26. Stated differently, thewire 26 may partially slice or completely slice through thesealant 24 to unseal thefirst component 12 from thesecond component 16. That is, an operator or machine may pull on thehandle 36 of thewire 26 and translate thewire 26 in thedirection 38 substantially parallel to thefirst sealing surface 100 and thesecond sealing surface 200 so that thewire 26 slices through and severs thesealant 24, unseals thesecond component 16 from thefirst component 12, and thereby separates thesecond component 16 from thefirst component 12. Beneficially, thewire 26 may sever thesealant 24 without damaging, e.g., fracturing, marring, and/or bending, thefirst flange 14 and thesecond flange 18. Therefore, upon the completion of maintenance operations, thesecond component 16 may be re-matable to thefirst component 12 after thewire 26 severs thesealant 24. - Referring now to
FIG. 3 , amethod 48 of unsealing the sealed assembly 10 (FIG. 1 ) is set forth herein. Themethod 48 may be useful for disassembling the second component 16 (FIG. 1 ) from the first component 12 (FIG. 1 ), e.g., during maintenance operations of the sealedassembly 10. - As described with reference to
FIG. 2 , the method 48 (FIG. 3 ) includes applying 50 (FIG. 3 ) asealant composition 52 onto thewire 26, wherein thewire 26 is disposed between and along thefirst flange 14 of thefirst component 12 and thesecond flange 18 of thesecond component 16. Suitable non-limiting examples of thesealant composition 52 include room-temperature vulcanizable sealant compositions and silicone sealant compositions. In one example, thesealant composition 52 is a room-temperaturevulcanizable sealant composition 52. Prior to applying 50, themethod 48 may include preforming 54 (FIG. 3 ) thewire 26 into the rigid,bent configuration 44 having the shape congruent with thesecond flange 18. Then, after preforming 54, thewire 26 may be placed onto thesecond flange 18. - Further, as best shown in
FIG. 2 , concurrent to or after thewire 26 is placed onto thesecond flange 18, each of the plurality offasteners 40 may be inserted into a respective one of the plurality of holes 42 (FIG. 1 ) defined by thefirst flange 14 andsecond flange 18 to thereby fasten thesecond component 16 to thefirst component 12. Subsequently, thesealant composition 52 may be applied onto thewire 26 so as to surround thewire 26 along thesecond flange 18. Thesealant composition 52 may be applied in any suitable manner, such as, but not limited to, applying 50 (FIG. 3 ) thesealant composition 52 through a nozzle (shown generally at 56 inFIG. 2 ). - Referring again to
FIG. 2 , after applying 50 (FIG. 3 ), the method 48 (FIG. 3 ) includes curing 58 (FIG. 3 ) thesealant composition 52 to form thesealant 24 between thefirst component 12 and thesecond component 16 such that thesecond component 16 is mated to thefirst component 12 to thereby form the sealedassembly 10. Curing 58 may include exposing thesealant composition 52 to ambient temperature for a curing duration, e.g., for from about 1 minute to about 10 minutes. As such, curing 58 may sealingly mate thefirst flange 14 to thesecond flange 18 and, in conjunction with the plurality offasteners 40, may form a fluid-tight seal between thefirst component 12 and thesecond component 16. - With continued reference to
FIG. 2 , the method 48 (FIG. 3 ) also includes, after curing 58 (FIG. 3 ), pulling 60 (FIG. 3 ) thewire 26 through thesealant 24 to sever thesealant 24 and thereby unseal the sealedassembly 10. As set forth above, pulling 60 may translate thewire 26 in thedirection 38 substantially parallel to thefirst sealing surface 100 and thesecond sealing surface 200. For example, pulling 60 may include translating thewire 26 by hand to thereby sever thesealant 24. That is, during repair operations wherein it is desirable to separate thefirst component 12 and thesecond component 16 from one another, an operator may pull thehandle 36 to thereby slice thewire 26 through thesealant 24 to unseal the sealedassembly 10. Subsequently, the plurality offasteners 40 may be unfastened so that thesecond component 16 may be removed from thefirst component 12. Therefore, pulling 60 may include protecting thefirst flange 14 and thesecond flange 18 from damage from, e.g., fracture, marring, and/or bending. - As such, with continued reference to
FIG. 2 , the method 48 (FIG. 3 ) may also include, after pulling 60 (FIG. 3 ), reforming 62 (FIG. 3 ) the sealedassembly 10. For example, after the conclusion of maintenance operations, an additional wire (not shown) may be again placed onto thesecond flange 18, thesealant composition 52 may be applied onto thewire 26, and thesecond flange 18 may be sealingly mated to thefirst flange 14 by abutting thefirst component 12 and thesecond component 16 and fastening the plurality offasteners 40. - The sealed assembly 10 (
FIGS. 1 and 2 ) and method 48 (FIG. 3 ) allow for simple and efficient separation of the first component 12 (FIGS. 1 and 2 ) and the second component 16 (FIGS. 1 and 2 ) without damaging the first flange 14 (FIGS. 1 and 2 ) or the second flange 18 (FIGS. 1 and 2 ). Further, the sealedassembly 10 andmethod 48 are especially suitable for applications requiringfirst components 12 andsecond components 16 formed from different materials. That is, the sealedassembly 10 andmethod 48 minimize breakage and/or damage ofcomponents assembly 10. Therefore, the sealedassembly 10 andmethod 48 allow for efficient re-assembly of the sealedassembly 10 after thefirst component 12 is unsealed from thesecond component 16. - While the best modes for carrying out the disclosure have been described in detail, those familiar with the art to which this disclosure relates will recognize various alternative designs and embodiments for practicing the disclosure within the scope of the appended claims.
